问题
I am testing equalizer in my Android Version 7.1.1 but it shows a Runtime Exception but It's perfectly working on below version 7.0.
When I try to initialize equalizer :
private static UUID EQUALIZER_UUID;
mp = MediaPlayer.create(this, R.raw.a);
mp.start();
if(hasEqualizer()) {
equalizer = new Equalizer(0, mp.getAudioSessionId());
equalizer = equalizerUtil.getEqualizer(mp);
Log.d("No. of Presets",String.valueOf(equalizer.getNumberOfPresets()));
}
public static boolean hasEqualizer() {
for (AudioEffect.Descriptor effect : AudioEffect.queryEffects()) {
if (EQUALIZER_UUID.equals(effect.type)) {
return true;
}
}
return false;
}
It Shows Error :
java.lang.RuntimeException: Cannot initialize effect engine for type: 0bed4300-ddd6-11db-8f34-0002a5d5c51b Error: -3

Caused by: java.lang.RuntimeException: Cannot initialize effect engine for type: 0bed4300-ddd6-11db-8f34-0002a5d5c51b Error: -3
I had tried various solutions available on - java.lang.RuntimeException: Cannot initialize effect engine for type: 0bed4300-ddd6-11db-8f34-0002a5d5c51b Error: -3, but Nothing works
Can someone have any ideas?

It looks like it might be an issue with getAudioSessionId() if a session ID isn't available yet. See this response on the thread linked below:
That means it hasn't been set yet. You can use player.setAudioDebugListener to listen for the ID being set (the ID will be passed via onAudioSessionId when it is).
